Giving my son my 00yz250 and I dont know if I want another 2 stroke or a 426 (going with the 426 for the green sticker). I havent ridden one so I have no idea what its like. We ride both track (just for fun, and trails). Can anyone tell me what its like to ride compared to my bike. Was thinking of going the DRZ400 route but I dont think thats what I am looking for. My main concerns are starting and 4 stroke maintenance although neither seems to be a big problem from what I read. I am about 5"10 and 200 lbs. Thanks for your help.
